hi,all,
I have got a problem when run opengles shader on mali-t760 gpu. In the fragment shader i calcuate the color as follow:
vec4 color = (((((Coef5*color+Coef4)*color + Coef3)*color+Coef2)*color + Coef1)*color+Coef)*color;
this formule is much slower than
vec4 color = coef*color; (almost 8ms slower.)
why this happen as other GPUs(such as PC gpu) do not have this problem which is just 2ms slower at most.
